    Vulnerability: Participatory Design, Older People and Researchers

    Get PDF
    Abstract Participatory design research is often used in work involving older people who are using digital technology. This type of research typically opens up both the researcher and the participant to vulnerabilities in the process. We discuss these issues of vulnerability as it relates to our current study using a local running group as platform for supporting older people in gaining confidence in integrating digital technologies in their everyday life. We discuss the over arching issue of older people, digital technology usage and participatory design. This provides the background for addressing points of awareness regarding empowerment, expectations, boundaries and loss for both the participants and the researcher

    Using Semantic Waves to Analyse the Effectiveness of Unplugged Computing Activities

    Get PDF
    We apply the notion of ‘semantic waves’ from Legitimation Code Theory (LCT), a powerful educational framework, to Computer Science Education. We consider two case studies exploring how a simple analysis can help improve learning activities. The case studies focus on unplugged activities used in the context of both teaching school students and teacher continuing professional development. We used a simple method based on LCT to analyse the activities in terms of their ‘semantic profiles’: changes in the context-dependence and complexity of the knowledge being taught.This led to improvements to the activities. We argue that ‘semantic waves’, or moves back and forth between concrete/simpler and abstract/complex knowledge, help show ways that an unplugged activity might be effective or not, and how small changes to the activities can make a difference in potentially offering a more fruitful learning experienc

    Past as global trade governance prelude: reconfiguring debate about reform of the multilateral trading system

    Get PDF
    This paper peers backwards into the history of the multilateral trading system and its development over the past half century as a means of considering what may lie beyond the horizon for the future of global trade governance. Its purpose is to underscore the necessity and urgency for root-and-branch reform of the multilateral trading system. It achieves this by comparing and contrasting the global trading system of 50 years ago with its modern-day equivalent and its likely future counterpart half-a-century hence. In so doing, the paper throws into sharp relief not only the inadequacies of global trade governance today but also the damaging consequences of not fundamentally reforming the system in the near future, with a particular emphasis on the past, present and future development of the world’s poorest and most marginalised countries

    Narrative perspective, person references, and evidentiality in clinical incident reports

    Clinical incident reporting provides opportunities for organisational learning, ideally leading to improved patient safety. However, this process requires healthcare professionals to record experiences where patients were harmed, or had the potential to be harmed. It also requires others to interpret the language used in order to make recommendations. We investigate the use of epistemic and evidential markers in incidents labelled as ‘user error’, in which a responsible individual is categorically implied, as opposed to other types of incidents where responsible individuals may not be tacitly assumed, such as ‘failure of sterilisation or contamination of equipment’ and ‘lack of suitably trained staff’. By analysing the frequency of various linguistic features related to authority and accountability, we provide insights into the pragmatics of clinical incident reporting. We find that user error reports differ from other categories of reports in that the identity of the narrator is obscured and the locus of agency is removed, and that this difference is irrespective to levels of patient harm. User error reports differ from other incident reports in the following statistically significant ways: they are more likely to be written using impersonal absent narration and feature significantly higher frequencies of epistemic markers of uncertainty and evidentiality

    The specification and analysis of use properties of a nuclear control system

    No full text
    The chapter explores a layered approach to the analysis of the Nuclear Power Plant Control System described in Chapter 4. A model is specified to allow the analysis of use-centred properties based on generic templates. User interface properties include: the visibility of state attributes, the clarity of the mode structure and the ease with which an action can be recovered from. Property templates are used as heuristics to ease the construction of requirements for the control system interface.Jose Creissac Campos and Michael Harrison were funded by project ref.

    Franchises lost and gained: post-coloniality and the development of women’s rights in Canada

    Get PDF
    The Canadian constitution is to some extent characterised by its focus on equality, and in particular gender equality. This development of women’s rights in Canada and the greater engagement of women as political actors is often presented as a steady linear process, moving forwards from post-enlightenment modernity. This article seeks to disturb this ‘discourse of the continuous,’ by using an analysis of the pre-confederation history of suffrage in Canada to both refute a simplistic linear view of women’s rights development and to argue for recognition of the Indigenous contribution to the history of women’s rights in Canada. The gain of franchise and suffrage movements in Canada in the late nineteenth and early twentieth century are, rightly, the focus of considerable study (Pauker 2015), This article takes an alternative perspective. Instead, it examines the exercise of earlier franchises in pre-confederation Canada. In particular it analyses why franchise was exercised more widely in Lower Canada and relates this to the context of the removal of franchises from women prior to confederation
